These hands-on problem-solving guides bring together the knowledge of international authors in the field to create a state-of-the-art picture of optical fiber sensors. They include technology overviews, survey applications, and describe measurement and implementation techniques. Helpful real-world case studies are also featured. Actual sensor performance examples provide guidance on measurement evaluations, environmental conditions, performance limitations, potential applications, and process-compatible formats, devices, and systems. Optical Fiber Sensors III: Components and Subsystems discusses the significance of recent fiber optic developments, including: • The Fiber Bragg grating — and its impact on the basics of sensing technology • The optical fiber amplifier — and its emergence as an important optical source when configured as a laser and as a broadband photoluminescent device • Distributed sensing — and its development at both the conceptual level and in the engineering of optical time-domain reflectometers • Chemical and environmental monitoring • Structural instrumentation and "smart" structures • Process control and engineering • Specialist industrial measurements
